http://www.vigo.lib.in.us/spc/townships/nevins.htm - a bit of information for around 1880 here.
The little village of Coal Bluff is situated on Sec. 8, R. 8. Daniel Webster first commenced to operate for coal on the present location of the village about 1871, and being successful, a village composed mainly of miners soon sprang up. A post-office was established June 8, 1876, with C. M. Stetson as postmaster, who still holds the office. Mr. Webster soon sold his mining interest to the Coal Bluff Mining Company, of Litchfield, Illinois. This company employ about fifty men and mine from 50 to 100 tons of coal per day. The mine is a slope and not a shaft, and the coal bed is about seven feet thick, extending through a hill. The deposit is nearly exhausted at present, when the company will remove to Fountain. Another mine is operated on a small scale below the Webster mine.
http://www.vigo.lib.in.us/ref/electronic_resources.htm - the local public library seems to have quite a bit of info, including some old history books for the area online.
Seeing your added info - this is 'James Marsh'? Jemima Joan Marsh's obituary is listed (1948) on the above library link. There's also a possible James Marsh d. 1926 instead of 1927 but the age is right. (You can get copies of the obituaries for $1 apiece). Also James J. Marsh, two records, late 1967 and early 1968, who I think might be the son (see below).
Also in 1920 in Vigo Co there appears to be James Marsh, b. 1854 (England), Jemima, b. 1869, and James J. Marsh b. 1902 Canada
1930, Terre Haute:
James J. Marsh 1903 (Canada)
Ethel M, 1905
James J, 1926
